The use of computer-based information is still expected to expand significantly worldwide. One of the technologies that have increased trust is a digital signature.

Introduction

In today’s world, managing electronic documents and sending and receiving electronic information is a big part of advertising and executive activities. The use of computer-based information is expanding significantly worldwide. One of the technologies that have increased trust is a digital signature. This encryption-based technique has led to the recognition of electronic information so that the identity of the document creator. And the comprehensiveness of its information can be reviewed and controlled.

Today, papers, which were the main carriers of important information, gradually give way to other ways of exchanging information. In fact, the paper has disadvantages such as slow and costly transfer of documents, and their archiving also creates many problems.

With the advancement of information technology, the conversion of traditional commerce to e-commerce. The exchange of documents in this type of business has become widespread. These documents often contain sensitive information such as legal contracts, confidential technologies, or financial transactions. These documents need to be encrypted to prevent the theft of computer thieves who are always on the lookout for documents in the electronic space.

 

How does a digital signature work?

Digital signatures are based on Public Key cryptography, also known as asymmetric cryptography. Using a public key algorithm such as RSA, two keys can be created that are mathematically related. One of which is a public key and the other a private key. To create a digital signature, the signing software (such as an email sending program) creates a hash (HASH) of the information to be signed.

The public key encrypts this spilled information. Encrypted spilled information, along with other information. Such as, the algorithm with which it is scrambled is called a digital signature.

The reason cryptographic information is encrypted instead of raw message or document is that a scrambled algorithm has the ability to make any information given to it a specific and constant size. Usually smaller than the length of the original content. Is wet. This speeds up the operation.

The amount of spilled data is separate and unique from the spilled data. Every change made to the data (even the smallest change) results in a different value, and this feature ensures that the signer’s public key maintains the information.

If the decrypted spill data was equal to the decrypted spill data, the information has not been tampered with since it was sent. If two different results are obtained, the data has changed in any way along the way and will be invalid.

A digital signature can be used for any message, whether or not it is encrypted. The recipient of the message can easily identify the sender of the message.

A digital signature prevents the signer from refusing to sign the submissions. This is because the digital signature per document with the signer is unique.
Probably a factor as to why they’re doing so poorly.

Conclusion

There was also talk of digital certificates, which I have avoided because of the complexities that may take you away from the original concept.
